Supporting roller replacing device capable of reducing abrasion

Abstract

The invention provides a supporting roller replacing device capable of reducing abrasion, and relates to the technical field of rolling mill auxiliary equipment, the supporting roller replacing device comprises a lifting frame, the lifting frame is composed of two vertical plates and a connecting rod, and supporting frames are arranged on the left side and the right side between the two vertical plates of the lifting frame. According to the invention, the transfer action and the replacement action of the supporting roller are linked and combined together in sequence through mechanical transmission to be carried out at one time, so that the trouble of step-by-step operation is saved; the upper clamping plate a is pulled through the sliding sleeve and is separated from the limiting of the elastic convex piece, and the supporting roller is automatically clamped by the upper clamping plate a under the elastic action of the extension spring, so that the overall use process of the equipment is simplified, and the problems that the supporting roller is difficult to keep balance in the transfer process, the position is easy to shift and the working efficiency is low are solved. The problems that in the prior art, the supporting rollers need to be lifted upwards, transfer actions and replacement actions of the supporting rollers need to be carried out step by step in a matched mode, the use efficiency of equipment is poor, in addition, the supporting rollers need to be clamped when completing upward lifting and transfer, and operation is tedious and inconvenient are solved.

Description

technical field [0001] The invention relates to the technical field of rolling mill auxiliary equipment, in particular to a support roll changing device capable of reducing wear. Background technique [0002] When the rolling mill equipment is working, the roll system is generally composed of backup rolls, intermediate rolls, work rolls, etc., and is an important part of the rolling mill equipment. The rolls in the roll system always have to bear the rolling force that changes in direction and size . The long-term use of the roll will cause fatigue wear or damage, and the roll needs to be maintained or replaced. [0003] However, as far as the current traditional support roll changing device is concerned, since the support roll is not easy to maintain balance during the transfer process, its position is prone to shift, and it will also affect the accuracy of the assembly of the replacement roll, and the transfer action and replacement action of the support roll It needs to...

The long-term use of the roll will cause fatigue wear or damage, and the roll needs to be maintained or replaced

[0003] However, as far as the current traditional support roll changing device is concerned, since the support roll is not easy to maintain balance during the transfer process, its position is prone to shift, and it will also affect the accuracy of the assembly of the replacement roll, and the transfer action and replacement action of the support roll It needs to be carried out step by step, resulting in poor use efficiency of the equipment. In addition, the support roller needs to be clamped when it is lifted up and transferred, which is cumbersome and inconvenient to operate
